I am not sure of the optical laws envolved, but sometimes bright dots show flare and are hard to use. I think this is caused by my astigmatism, but I don't know why it is worse in some scopes and not others. I would worry about the dot reticle but I believe the triangle reticle would be useful.
The Accupoints do not have batteries. They have a port (window) where ambient light comes in, which is then carried to the reticle by a fiber optic. You can run the port wide open, or you can close it off completely, or anything in between.
The "flare" you are talking about is usually not a problem with them, but can be if the port is in direct sunlight. It takes about 2 seconds to turn the ring to restrict the light coming in. Problem solved.
My favorite scopes are my NF's, but not for hunting. The Trijicon with the fiber optic dot is my favorite for hunting.
